brake-lights not working
 

i have 88 GLE .
for some reason my both brake lights not working. the light at the top (rear window )
works.
i have changed bulbs -clean the contact -check wires etc. but all seems o.k.
what could be wrong ? any help will be greatly appreciated.

I just bought my 240 this evening and was informed of the same thing. ALL of the other lights work though, on mine, including the running lights.

Interested to see what comes back from your question.
